# F4PGA Architecture Definitions



  

  

  



**This repository is focused on the development of architecture support in F4PGA. Start with the [![Examples (for Users)](https://img.shields.io/website?longCache=true&style=flat-square&label=F4PGA%20Examples%20for%20Users&up_color=white&up_message=%E2%9E%9A&url=https%3A%2F%2Ff4pga-examples.readthedocs.io%2Fen%2Flatest%2Findex.html&labelColor=231f20)](https://f4pga-examples.readthedocs.io) if you are looking to use the

tools.**

This repo contains documentation of various FPGA architectures, it is currently concentrating on:

* Lattice

  * [iCE40](lattice/ice40)

  * [ECP5](lattice/ecp5)

* AMD/Xilinx

  * [Series 7](xilinx/xc7) (Artix, Kintex and Zynq)

* [QuickLogic](quicklogic)

It includes:

* Black box part definitions

* Verilog To Routing architecture definitions

* Documentation for humans

* Verilog simulations

The aim is to gather useful documentation (both human and machine readable) about the primitives and routing

infrastructure for these architectures.

We hope this enables growth in the open source FPGA tools space.
